The Gardeners Almanac

The place to find out what to do in the garden this week
My Back Garden

Growing 'Indoors' or 'Under glass' in June


It should be quite safe at this time of year to move many tender plant varieties outdoors for the summer.

It is also a good time to replace the compost in many house plants, and to commence feeding programmes.

Many young plants will be developing and may require stopping to promote bushyness and flower production.

Note: As with most advice on gardening the advisors location will often influence the content of the advice.

To alleviate this problem I have produced this chart indicating how you can make adjustments to the timing of events as seen in this website.

I hope you find this useful! .......Tg
